Douglas Reindl, P.E., Ph.D.
Doug has interests and expertise in a number of areas related to industrial refrigeration systems that include system safety, optimization, assessment of design alternatives, conceptual design, energy conservation measures, system modeling, and field evaluation. As the founding director of the IRC, he leads the IRC's activities in the areas of research, knowledge transfer, and technical assistance for IRC members.
In addition to directing the IRC, Doug is a Professor in the College of Engineering with appointments in the Department of Engineering Professional Development (EPD) and Mechanical Engineering. Through EPD, he has developed an internationally-recognized series of ammonia refrigeration education programs. The ammonia programs provide attendees valuable information they can take back to their jobs for immediate application to improve the safety, efficiency, and cost-effectiveness of refrigeration systems. He has also led the development of a Process Safety Management "Best Practices" series of courses that provide state-of-the-art information on effectively managing refrigeration system safety.
He is a registered Professional Engineer in the State of Wisconsin, the immediate past chairman of ASHRAE's SSPC Standard 15 (Safety Standard for Refrigeration Systems), past chairman of ASHRAE Technical Committee 6.9 (Thermal Storage) and past vice-chair of ASHRAE GPC-2 - Engineering Analysis of Experimental Data. He is a member of commission D1 (Refrigerated Storage) at the International Institute of Refrigeration (IIR) and the International Institute of Ammonia Refrigeration (IIAR).
Todd Jekel, P.E., Ph.D.
Todd has been at the IRC since 1997. All of his degrees are in mechanical engineering. Todd has extensive experience in modeling and analysis of industrial refrigeration systems with a focus on economics of energy efficiency measures . He is also interested in refrigeration load calculation, refrigeration system component modeling, accumulator design and the two-phase flow are some of his special interests in industrial refrigeration.
Todd is a member of ASHRAE and IIAR.
Todd has been involved in many site visits, and research including:
Dan has interests and expertise in a number of areas related to industrial refrigeration systems, refrigerated structures and related activities. Areas of interest include refrigerated warehouses, frost heave protection systems, nondestructive testing, mechanical integrity, refrigerant phaseout issues, refrigerant selection, long range refrigeration system planning and refrigeration system design. Related areas of interest include food processing, food preservation, industry trends and production/energy-use information.
His industrial refrigeration audit experience has included end-use applications involving distribution warehouses, public warehouses, productions coolers, production freezers, dairy processing, juice. meat, vegetable, bakery and many others.
Dan also provides seminar training and technical presentations to a variety of audiences.
Dan is a members of IIAR and ASHRAE, where he is a former chair of T.C. 10.5 (Refrigerated Distribution and Storage Facilities) and current member of the Refrigeration Committee.
James L. Denkmann
Jim assists the Center by providing training for EPRI-member utilities in the areas of ammonia refrigeration, high efficiency chillers, thermal storage, space conditioning selection of HVAC equipment for commercial applications and fundamental HVAC information. Jim has also performed research for EPRI, including investigating the possibility of retrofitting rooftop air conditioning units to utilize thermal storage technology.
Jim has an extensive background in HVAC systems for large retail, office, and healthcare facilities as well as thorough knowledge of thermal storage applications. Jim formerly worked for Condaire, Inc. before becoming a project manager for Wm. Brookman & Associates and then Holabird & Root, a major HVAC contractor in Chicago, Illinois.
He is the founder of Denkmann Thermal Storage, Ltd., a firm specializing in thermal storage design and technologies.
Sandy Klein, Ph.D.
Professor Klein has been on the faculty of the Mechanical Engineering Department at University of Wisconsin - Madison since 1977. He is associated with the Solar Energy Laboratory and has been involved in many studies of solar and other types of energy systems.
He is the author or co-author of more than 120 publications relating to the analysis of energy systems. Professor Klein's current research interests are on thermodynamics, air quality control, refrigerant properties, and refrigeration systems.
He has participated in research projects relating to refrigeration for indoor ice skating and food storage in refrigerated warehouses. He is one of the contributors to the REFPROP 6 refrigerant properties program that is distributed by the National Institute for Standards and Technology. In addition, he has also actively involved in the development of engineering computer tools for both instruction and research.
He is the primary author of the finite element heat transfer program, FEHT, and the general engineering equation solving program, EES. Professor Klein is a Fellow of the American Solar Energy Society and the American Society of Heating, Refrigeration, and Air-Conditioning Engineers (ASHRAE).
